EXIF v2.31 (p49) defined time-zone offset fields in 2016 and the XMP time-zone guidelines (p33-34) also consider time-zones. The implementation in cameras and programs is rather minimalist at the moment. See also my answer to an older question: What do you do with your camera clock time in relation to time zones?

What Windows displays under the "Date Taken" property isn't an embedded tag. It fills that property from a number of tags depending upon the file type. For example, for a JPG, Windows will use any of these tags: EXIF:DateTimeOriginal, XMP:DateTimeOriginal, EXIF:CreateDate, and the system FileCreateDate. ExifTool can create an EXIF:DateTimeOriginal tag in a ...

There's already a similar question on the ExifTool forums. It can be done using two sequential ExifTool commands. First, make sure all the date to the same exiftool -datetimeoriginal="2015:02:22 00:00:00" DIR And then increment the time on each exiftool '-datetimeoriginal+<0:0:${filesequence}0' DIR 8 ExifTool is my go-to tool for time-shifting photos. Assuming Windows, to add 1 hour to all date/time fields stored in the photo metadata: exiftool.exe -AllDates+=1 C:\path\to\folder\of\photos or to subtract one hour: exiftool.exe -AllDates-=1 C:\path\to\folder\of\photos By default, this will make a copy of the original as backup before modification. To ... 7 Very recent versions of PNG support EXIF, but a lot of software still does not understand or work with it. The lack of a standardized metadata block has been one of its big disadvantages for photography. If you need a lossless format which preserves (very-similar-to-EXIF, since it's the basis for EXIF) metadata, try TIFF. The downside, though, is that TIFF ... 7 Yes, it is the time at which the location was determined. That may be a second before the picture was taken, but it could be much more, if for example you are in a canyon and the GPS is unable to make a fix. 6 As I just found out, this is a bug in Lightroom, more than a year old, but still not fixed. Please see this thread on the support forums where an employee of Adobe confirmed the bug to be linked to the USB connection with the camera. They also recommend to use a card reader instead of the USB connection. 6 Unfortunately not. Most cameras only have a 'dumb' timezone-ignorant clock. You do of course also have no guarantee that the clock is set right, so the timestamp in the EXIF data may be wrong anyway, even if you know or assume the correct time zone. What you might do to improve your interpretation of the EXIF timestamp is, if the image is geo-tagged, to ... 6 CIPA DC- 008 is the standard for Exif 2.2. Of note it makes no mention of "timezone." "GMT" is also not mentioned either. The term "UTC" does appear but only specifies the GPS time is recorded as such. Pedants may note that this is slightly misleading since GPS time is not identical to UTC My point, in short, is that omission of timezone is likely not ... 5 With regards to EXIF v2.31 (p49) time-zone integration (2016) and XMP time-zone guidelines (p34) it might make sense to look at this problem once more. Local time is important especially in the human-based interaction with pictures. Looking at a sunset photo one expects the clock to show something in the second half of the day, for breakfast photos rather ... 4 This is very helpful, it shows many available tools: http://petapixel.com/2012/11/05/how-to-fix-your-timestamps-if-you-forgot-to-update-your-camera-for-daylight-savings/ namely how to use Adobe Lightroom, Picasa, Jhead, ExifTool and Exifer to shift the date. Personally I use ExifTool, and Exiv2, which works on MacOSX to do the following in the terminal: ... 4 Please check out http://jambula.sourceforge.net/ to batch insert shooting date/time/comment on a jpeg image in different formats and languages. A special feature is that the date stamp is lossless. It is supported on Linux and Mac also. 4 Since the best answers use non-Windows syntax, I will here post their code converted for Microsoft Windows. @StarGeek solution, very fast and simple: First set a base timestamp to all images: exiftool -datetimeoriginal="2015:01:01 12:00:00" DIR (DIR is the name of the folder containing all images.) Then assign incremental timestamps: exiftool "-... 4 I don't think any significant software which uses this. The EXIF standard is to assume that the time zone matches the correct one for the location where the photo was taken. Most cameras have ad hoc non-standard tags for dealing with this; for example, my Pentax camera sets World Time Location. However, EXIF isn't all there is, and in fact I think most ... 4 Yes, it is possible. The ideal case would be if it was visible from your home so that you can leave a tripod stationary and just attach the camera when you need to. If the construction site is somewhere else, however, you can't use the tripod to mark a location. Better try to think of a good location to shoot from with something that won't move for a while - ... 4 The Nikon D5100 uses a rechargeable internal clock battery. It should have enough charge to give you 3 months to charge the main battery. A main battery that is almost completely empty, should also have enough power left to keep the clock running for months or even years. There is probably a problem with your internal battery, or a contact to it. The ... 3 Some upper tier Canon cameras allow you to set the length of time the viewfinder display remains active when no buttons are pressed. A quick look at the EOS 70D Instruction Manual indicates this is not an option with the 70D. You can adjust the time exposure information is actively displayed while in Live View. There are a few ways to keep the viewfinder ... 3 Well, I didn't post my bash answer because the question specifically asked about a Windows solution, but since two other people did, here's what I came up with: for file in *.jpg do exiftool -DateTimeOriginal="1111:11:11 00:00:00"$file exiftool -DateTimeOriginal+="00:00:${file:6:4}0"$file done Avoids messing with the date command. :) Note that in ...

Try Irfanview. It is freeware (AFAIR) and has a very flexible batch renaming system. Other than that I would try writing a script, something along the lines of for X in $(seq -w 0 20) ; do plus=$(expr $X \* 10) exiftool -alldates+="0:0:0 0:0:$plus" image_\$X.jpg done The first line creates a loop through the numbers in the file names that you have, eg. ...

No, the GoPro Hero 3+ does not have a self-timer mode. But there are several ways of taking 'selfie' photos: You could set the Hero to timelapse mode, ie taking a photo every 0.5, 1 or 2 seconds. Press the shutter, and it will start taking a series of photos. So you can then get in position for the selfie, and it will get a number of photos of you. You can ...

well, just this week i found two rolls of film. a 35mm kodacolor 24 exposure. had no idea when it was from. just got the negs and a cd back. turns out the pics are from summer of 1990. very grainy and very washed out colors. but, adobe photoshop "perked" up the pictures and i'm glad i got them developed. the other roll is even older. it's kodacolor ...

RAW files contain more data than JPEGs so saving/moving the files takes more time. The RAW and JPEG files should be the same resolution, but per pixel there is more data. Connecting to a PC isn't going to make it take less time; it may actually take longer because the speed of writing to the SD or CF card is probably faster than the USB connection to the ...

Most cameras have a capacitor or internal battery that keeps the clock and settings active while the battery is being changed. If the camera is left with a dead battery for a very long time, the capacitor or battery may become fully discharged and dysfunctional.

It is closely related to the determination of B&W film speed, which is specified in the standards ISO 6 and ISO 2240 and based on sensiometric density and contrast measurements of the negative. The actual speed of a black and white film can only be measured after it has been developed and the reference development times are defined, so that the negative ...

Your system clock should be set to the local time. If that is not the case, it has to be fixed since this is how Windows likes to work. For Lightroom to interpret the time correctly, your camera should be set to the local time as well. IIRC, Canon cameras do not have a concept for timezone or home time. Assuming both of these issues are corrected, you may ...

This sounds like a homework project, where a tutor would set a broad theme and want to see your ideas and how they develop. So I'm going to avoid giving you direct ideas because it's meant to be your work not ours! Generally if you want to explore a concept and are stuck then breaking down your creative process a bit will help. Here are a few ideas I ...

While I can't think of a way to do it with the built-in functions of Lightroom, it can be done with the help of the LR/Transporter Lightroom Plug-in (donationware; free version restricted to modifying 5 images at a time). If you don't choose to donate, you'll need to repeat the steps 2…4 below for every 5 images until you're through your whole collection. We'...

There is one internal battery, which take care about the clock. Check please this web page, step 13, right image. If this battery is discharged (it is not rechargeable) lost of settings as clock is expected behavior. IMHO there is no way to change it by self, so my humble recommendation is to contact GoPro service

Short answer: Yes. Longer answer: Make sure you shoot with the same focal length (and - even better - using same lens). You'll have to note a couple of points in order to shoot the same frame (f.e. upper left point in viewer, central focusing point, and lower left point). However your photos still will not be perfectly aligned and you'll have to use some ...

Yes, you can swipe in from the right to select shoot modes. Timelapse is an option and you can even select how often it shoots a frame. https://www.camerajabber.com/shoot-time-lapse-video-gopro-hero5-black/
